I am using the following fan : ME70201V1-000U-A99, which should be supplied at 12 V and consumes about 150 mA.
My schematics is as follows :
Than fan is connected to X3. PWM_VENTILO is the PWM output of a microcontroller.
If PWM_VENTILO is a simple high GPIO output, it spins at full speed. But if I try to control its speed with the PWM, it does not spin. I have tried different frequencies (some Hz to 20 kHz) and different duty cycles, I always have the same result : it gets stuck and never spins. At low frequency, it kinda works, but the spin is irregular. The MOSFET transistor accepts voltages and current which are necessary.
Is there something I am doing wrong ?
